It aims to offer capture and playback for both audio and video with minimal latency and support for PulseAudio, JACK, ALSA and GStreamer-based applications The daemon based on the framework can be configured to be both an audio server (with PulseAudio and JACK features) and a video capture server. To create a loopback device using pw-loopback, users need to specify the source and sink ports using their port IDs. This can be done either by copying the system file under /etc/pulse to the user's configuration directory, or by creating a new file that includes it with the syntax.
